Optimal PMU placement for power system restoration
2015 Clemson University Power Systems Conference (PSC), 2015PMU placement is important to achieve full system observability. Traditional PMU placement algorithms only work for systems in normal condition. During power system restoration, system topology and condition change in each step. Synchrophsors can help to improve the reliability and efficiency of restoration strategy. However, the original PMU placement

Optimal placement of PMUs with limited number of channels
Electric Power Systems Research, 2012Abstract This paper proposes an approach for optimal placement of phasor measurement units (PMUs). It takes into account the availability of PMU measuring channels, and possible system contingencies like single measurement or branch outage. In order to solve the optimization problem, cellular genetic algorithm is applied.

Optimal PMU placement for state estimation robustness
IEEE PES Innovative Smart Grid Technologies, Europe, 2014Given a sufficient number of properly placed synchronized voltage and current phasor measurements, an L1 estimator (also known as the Least Absolute Value or LAV estimator) can be shown to be robust against gross measurement errors. This paper is concerned about the placement of phasor measurement units (PMU) in order to establish a desired level of ...

Optimal PMU placement: A comprehensive literature review
2011 IEEE Power and Energy Society General Meeting, 2011This review outlines the benefits that Phasor Measurement Unit (PMU) integration has on the power network. It reviews past optimal placement techniques covering meta-heuristic and deterministic algorithms. Three best performing algorithms are chosen in terms of minimum required number of PMUs for full system observability.

Comparison of different methods for optimal placement of PMUs
2009 IEEE Bucharest PowerTech, 2009The paper compares three different methods for optimal placement of PMUs. The objective of the placement methods is to provide the maximum observability information of the electromechanical modes of interest. The first method is based on the observability factor analysis, the second on the sequential orthogonalization algorithm and the third combines ...

Optimal placement of PMUs with limited number of channels
2011 North American Power Symposium, 2011The Phasor Measurement Units (PMUs) will enable the state estimation of a power distribution network provided the network is observable. So far in solving the Optimal PMU Placement (OPP) problem, it was assumed that the PMUs have sufficient number of channels such that a PMU placement on any node would make all the neighboring nodes observable.

Harmonic source identification with optimal placement of PMUs
2016 IEEE 1st International Conference on Power Electronics, Intelligent Control and Energy Systems (ICPEICES), 2016A power system consists of linear as well as nonlinear loads but with the advancement in power electronics, the amount of non-linear devices are increasing day by day. This increment leads us to take into account their adverse effects on the power system as it causes the power system signals to carry different frequency components, which generate ...

Optimal PMU Placement Using Stochastic Methods
2019 IEEE Power & Energy Society General Meeting (PESGM), 2019Phasor Measurement Units (PMUs) collect high-precision voltage and current data in order to monitor the performance of a power system. However, it is expensive to implement PMUs on every bus within a power system. Optimal PMU placement (OPP) becomes necessary to minimize the number of PMUs implemented while maintaining full observability of the network.
